I mean, I hate sort of a simple view of atoms as little balls going around each other, because they're not.
They're waves of energy.
But the gravity actually crushes the electrons into the nucleus.
They combine with protons to become neutrons.
So they're mainly little balls of neutrons.
But we do... There you go.
You see the big question mark there at the core?
So here's the problem.
You run our basic laws of physics, our understanding of how particles work, and you get to the density of a neutron core, and the equations don't work.
They're not making the right predictions.
We can tell that there is actually a really great NASA video I would suggest you watch.
It's called The Interior of a Neutron Star.
Well, I can help you find it, but it basically says that the...
The models we have about how matter works at that sort of density, none of them give the right predictions for the size of the neutron star.
We don't have the right physics for it yet.
So we run our physics and we see if you have this much volume and this much mass, what should that interior be like?
And none of our current models of how matter works gives us the right observations, gives us the right size.
Well, for one thing, you know, what you're probably looking at inside a neutron star is some type of interaction of quarks, the actual sort of building blocks of neutrons and protons, the particles that make up protons and neutrons.
Ooh, that's cool.
What is that?
